Product Specifications

The WY5W 12V 5W AMBER halogen lamp with a base specification of W2.1×9.5D is a low-voltage medium-power dedicated light source designed specifically for amber warning or identification lighting, and is also a common model for vehicle signal lighting scenarios. Among the specifications, WY5W is the standardized model code: the letter "W" represents the halogen light source type, "Y" corresponds to the amber light color, and "5W" clearly indicates a rated power of 5 watts with a rated voltage of 12 volts; the suffix "AMBER" further emphasizes that its luminous color is amber (the color temperature is usually in the range of 2000K–2500K, and the light presents a warm yellow-orange hue with a striking warning effect); W2.1×9.5D refers to the specification of its dedicated pin-type base, where "W2.1" indicates that the width of the base pins is 2.1 millimeters, and "9.5D" indicates that the length (depth) of the base pins is 9.5 millimeters. This base is a universal snap-in pin structure, suitable for most standardized slot-type lamp holders. It can be connected by direct plugging and unplugging without welding, featuring convenient replacement and strong compatibility.

Relying on halogen cycle technology, this lamp can effectively slow down the evaporation loss of the tungsten filament. Compared with ordinary colored incandescent lamps of the same power, it has higher luminous efficiency and better color fastness, and is not prone to fading and darkening; although the color rendering index is slightly lower than that of conventional white light halogen lamps due to the colored filter layer, it is fully sufficient for warning and identification lighting needs. The 12V low-voltage power supply ensures the safety of use, especially suitable for enclosed and human-accessible scenarios such as automobiles. During use, it needs to be matched with a 12V DC or regulated AC power supply to avoid overvoltage operation; during installation and replacement, it is strictly forbidden to directly touch the glass tube with hands to prevent local overheating caused by residual fingerprint grease and shorten the service life of the lamp. It is widely used in scenarios such as car front and rear position lights, side marker lights, turn signal auxiliary lights, as well as warning indicator lights for industrial equipment.
